Introduction
When it comes to motion sensing, InvenSense’s MPU-6000 and MPU-6050 are among the most widely adopted MEMS (Micro-Electro-Mechanical Systems) devices. They integrate a 3-axis gyroscope and a 3-axis accelerometer on a single chip, making them a compact and cost-effective solution for consumer and industrial applications.

2. Features
2.1 Gyroscope Features
The triple-axis MEMS gyroscope in the MPU-60X0 includes a wide range of features:
Digital-output X-, Y-, and Z-Axis angular rate sensors (gyroscopes) with a user-programmable full scale range of ±250, ±500, ±1000, and ±2000°/sec
External sync signal connected to the FSYNC pin supports image, video and GPS synchronization
Integrated 16-bit ADCs enable simultaneous sampling of gyros
Enhanced bias and sensitivity temperature stability reduces the need for user calibration
Improved low-frequency noise performance
Digitally-programmable low-pass filter
Gyroscope operating current: 3.6mA
Standby current: 5µA
Factory calibrated sensitivity scale factor
User self-test
2.2 Accelerometer Features
The triple-axis MEMS accelerometer in MPU-60X0 includes a wide range of features:
Digital-output triple-axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g
Integrated 16-bit ADCs enable simultaneous sampling of accelerometers while requiring no external multiplexer
Accelerometer normal operating current: 500µA
Low power accelerometer mode current: 10µA at 1.25Hz, 20µA at 5Hz, 60µA at 20Hz, 110µA at 40Hz
Orientation detection and signaling
Tap detection
User-programmable interrupts
High-G interrupt
User self-test
2.3 Additional Features
The MPU-60X0 includes the following additional features:
9-Axis MotionFusion by the on-chip Digital Motion Processor (DMP)
Auxiliary master I2C bus for reading data from external sensors (e.g., magnetometer)
3.9mA operating current when all 6 motion sensing axes and the DMP are enabled
VDD supply voltage range of 2.375V-3.46V
Flexible VLOGIC reference voltage supports multiple I2C interface voltages (MPU-6050 only)
Smallest and thinnest QFN package for portable devices: 4x4x0.9mm
Minimal cross-axis sensitivity between the accelerometer and gyroscope axes
1024 byte FIFO buffer reduces power consumption by allowing host processor to read the data in bursts and then go into a low-power mode as the MPU collects more data
Digital-output temperature sensor
User-programmable digital filters for gyroscope, accelerometer, and temp sensor
10,000 g shock tolerant
400kHz Fast Mode I2C for communicating with all registers
1MHz SPI serial interface for communicating with all registers (MPU-6000 only)
20MHz SPI serial interface for reading sensor and interrupt registers (MPU-6000 only)
MEMS structure hermetically sealed and bonded at wafer level
RoHS and Green compliant
